Impaired pupillary sensitivity in diabetic patients and correlation with visual outcome in cataract surgery.
Article in BMC ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate the relationship between pupillary response and diabetic characteristics in cataract patients and explore whether impaired pupillary function may impact cataract surgical outcomes and visual recovery in diabetic patients.
methodsThis prospective study included 362 participants (133 diabetic patients and 229 controls) who underwent cataract surgery. Diabetic patients were stratified by disease duration (≤ 1 year, 1-10 years, > 10 years). Pupil parameters and Visual quality metrics including higher-order aberrations (HOA), Strehl ratio (SR), and area ratio (AR) were evaluated using the OPD-Scan III aberrometer preoperatively and at 1 day, 1 week, and 1 month postoperatively.
resultsScotopic pupil diameter (PD) demonstrated a progressive decline with increasing diabetes duration. Patients with duration > 10 years showed significantly smaller scotopic pupils compared to controls (p < 0.0001) and shorter-duration subgroups (p < 0.01). PD difference deteriorated progressively in patients with duration > 1 year (p < 0.0001). Linear regression revealed that each 1% increase in HbA1c was associated with a 0.10 mm decrease in PD difference (β=-0.103, p < 0.001) and reduced scotopic PD (β=-0.112, p = 0.025). Postoperative visual quality parameters (HOA, SR, AR) showed comparable improvement between diabetic and control groups at all time points (p > 0.05), with diabetes duration showing minimal influence on outcomes.
conclusionDiabetic patients exhibit reduced pupillary sensitivity, particularly affecting scotopic pupil dilation, significantly associated with elevated HbA1c levels and longer diabetes duration. Postoperative improvements in visual quality of diabetic patients are comparable to those of non-diabetic patients, supporting use of functional intraocular lenses.
